If you could magically choose what 2 new reasonable things the Raspberry Pi 5 would have, that the Raspberry Pi 4 doesn’t have, what would that be? Not 3 things! That would be too ask too much. You can also consider a CM4 to be a Raspberry Pi 4, for the sake of this thread.
I’m going to say:
- Faster ARM CPU
- M.2 SATA slot
- A fully open source firmware stack.
- A direct* kill switch for bluetooth/wifi.
* Cuts power by breaking the circuit solely through a jumper or basic switch with no software or way of being circumvented by hardware or software.
- 8GB of RAM on the base model.
- maybe a 1x PCIe slot
I’d even take a RPi 4 rebadged as an RPi 5 if I could have free, libre, and open firmware and software stacks.
Expandable ram ( up to 32Gb)
Killswitches (as said by @Ulfnic )
You forgot to mention “available stock”.
I second the PCI slot, and request an open source video card with OS drivers for some ARM gaming
- fm radio
- sticker printer
(seriously: 1. better connectivity for storage (m2 or sata) 2. better heat management)
